CROSS-REFERENCE TO RELATED PATENT APPLICATION

This patent application is a continuation of U.S. patent applicationSer. No. 16/719,629, filed Dec. 18, 2019, which claims the benefit ofU.S. Provisional Patent Application No. 62/782,155, filed Dec. 19, 2018,the entire teachings and disclosure of which are incorporated herein byreference thereto.

FIELD OF THE INVENTION

This invention generally relates to multi-port valves, and moreparticularly to multi-port valves having multiple inlet and outlet portsto control flow in different planes.

BACKGROUND OF THE INVENTION

Multi-port valves are used in a variety of industries and applications.Such valves include one or more inlet ports and one or more outletports. A valve member disposed within a housing of the valve isresponsible for governing the flow between the various ports. A portionof the valve member, e.g. a valve stem, protrudes from the housing andis acted upon by an actuator attached to the multi-port valve. Asresult, the actuator governs the position of the valve member within thehousing, which in turn governs the flow between the various ports.

Such multi-port valves advantageously provide a single flow device whichcan effectively replace multiple flow devices which only employ a singleinlet and a single outlet. However, such multi-port valves are notwithout their own drawbacks. For example, the overall complexity of thevalve increases as the number of ports increases. This can lead torelatively high part count assemblies. Further, this complexity inconstruction also results in a more complex manufacturing process formaking the valve. Indeed, the multiple ports are associated withmultiple inlets and outlets of the valve which must be welded onto ahousing. Further the desired fitting for each inlet and outlet must alsobe welded on to its respective inlet or outlet.

Such welded up assemblies increase the number of potential leak paths ofthe valve. Further, to achieve such welds, special machining steps areoften needed at the inlets and outlets as well as the housing to ensurethere is a tight fit between these components for subsequent welding.

Furthermore, a number of individual seals are required to effectivelyseal the various ports of the multi-port valve off from one another.These multiple seals also lead to an increase in overall cost andcomplexity of the multi-port valve.

Multi-port valves that overcome these issues are available from theassignee of the instant application, and are described in U.S. Pat. No.9,212,751 (“Valve system and method” by Allan R. McLane et al.), issuedDec. 15, 2015, and co-pending U.S. patent application Ser. No.15/945,173 (Publication No. 2018/0292016, “Multi-port valve” by JoeLedvora et al.), filed Apr. 4, 2018, and claiming priority to U.S.Provisional Application No. 62/483,167, filed Apr. 7, 2017, theteachings and disclosure of which are hereby incorporated in theirentireties by reference thereto.

In many applications that utilize such multi-port valves, fluid flow inmultiple planes is required and typically provided via the externalplumbing in the fluid control system. Unfortunately, the use of suchexternal plumbing greatly increases the required volume or footprint ofthe overall fluid control system, and can create problems necessitatingre-routing and re-locating of other components in its or other systemsthat need to occupy that volume.

Accordingly, there is a need in the art for a multi-port valve thatprovides multi-planar fluid flow and control within the volume of thevalve itself. Embodiments of the present invention provide such amulti-port multi-plane valve. These and other advantages of theinvention, as well as additional inventive features, will be apparentfrom the description of the invention provided herein.

BRIEF SUMMARY OF THE INVENTION

In one aspect, embodiments of the present invention provide a multi-portmulti-plane valve having a reduced part count and a reduced costrelative to prior designs, and that provides multi-planar fluid flow andcontrol. An embodiment of such a multi-port multi-plane valve includes ahousing. The housing defines an internal cavity. The housing furtherincludes a plurality of ports, at least one of which lies in a differentplane from the other(s). Preferably, at least one of the ports lies in aplan normal to the plane of the other ports. Each of the plurality ofports is in communication with the internal cavity.

A preferred embodiment also includes a shell body rotatably disposedwithin the internal cavity. This shell body is configured to provideflow between different ports existing in the same plane and betweendifferent ports existing in different planes based on its angularposition within the valve housing.

A seal member is also provided which has a plurality of openings andsurrounds the shell body such that it circumscribes the shell bodywithin the internal cavity.

DETAILED DESCRIPTION OF THE INVENTION

Turning now to the figures, as will be understood from the following,embodiments of a multi-port multi-plane valve assembly and itsassociated multi-port multi-plane valve are described herein. Themulti-port multi-plane valve advantageously overcomes existing problemsin the art by presenting an overall construction with a reduced partcount, a reduced number of potential leak paths, a reduction in overallassembly time and cost, and reduced external plumbing to provide fluidflow and control in multiple planes.

As discussed in the above identified co-pending U.S. patent applicationSer. No. 15/945,173 (Publication No. 2018/0292016, “Multi-port valve” byJoe Ledvora et al.), filed Apr. 4, 2018, the teachings and disclosure ofwhich is hereby incorporated in its entirety by reference thereto,multi-port valve assemblies typically, as here, include an actuator (notshown herein) mounted to the multi-port valve. The actuator isresponsible for actuating a valve member (i.e., a shell body asdescribed below) which in turn governs the flow characteristics throughthe valve. The actuator may be any style of actuator typically used invalve actuation, e.g., rotary, linear, etc., and may rely on any type ofpower source typically used in valve actuation, e.g., electric,hydraulic, and pneumatic, etc. Monitoring of the rotational position ofthe valving member may also utilize any type of position sensing, e.g.,via a Hall-effect sensor, potentiometer, stepper motor control, etc. Assuch, the actuator and position sensing are non-limiting on theinvention herein.

Turning now to FIG. 1, an embodiment of the multi-port multi-plane valve32. Valve 32 includes a housing 40. In one advantageous implementationof the invention, housing 40 is formed as a single piece. By “formed asa single piece” it is meant that the main body of housing 40 and itsassociated ports are not an assembly of separate components which aresubsequently joined together by a joining process, e.g., welding, as isdone in conventional valve housings. Rather, housing 40 is formed as asingle unitary piece by any process capable of achieving such aconfiguration, e.g. injection molding, 3D printing, etc. However, it iscontemplated by the teachings herein that housing 40 may be embodied asan assembly of separate components which are subsequently joinedtogether by a joining process.

As illustrated, housing 40 includes a plurality of ports, in particular,a first port 42, a second port 44, a third port 46, a fourth port 48,and a fifth port 50 (see FIG. 7) that lies in a plane or along an axisthat is normal to the plane of the other four ports 42, 44, 46, 48 inthe illustrated embodiment. Of course those skilled in the art willrecognize that other angles may be provided. Each of the ports 42, 44,46, 48, 50 are in fluid communication with an internal cavity 56 ofhousing 40. Further, each of ports 42, 44, 46, 48, 50 may function as aninlet or an outlet, or both, of valve 32.

Still referring to FIG. 1, internal cavity 56 receives a generallycylindrical shell body 58 which operates as a valve member forcontrolling the flows between the plurality of ports 42, 44, 46, 48, 50.A seal member 60 is also received in cavity 56 and surrounds the outerperiphery of shell body 58. This seal member 58 is a continuouscylindrical element, except for the openings formed therein. As will bediscussed below, seal member 60 is a single piece seal whichadvantageously creates a seal for each of the plurality of ports 42, 44,46, 48 to prevent unintended cross flow or short circuiting.

Seal member 60 also advantageously entirely seals internal cavity 56,such that no additional seals need be associated with port 50 or a cover62 (see FIG. 7) of valve 32. It is possible, however, that seal member60 may also be formed as separate seal segments which immediately nextto one another in the circumferential direction, which together define aseal member which surrounds the shell body 58. The term “seal member” asused herein includes both configurations, i.e. a single unitary sealmember, or a seal member formed of a plurality seal segments.

Shell body 58 includes a plurality of openings. The openings of sealmember 60 remain statically aligned with ports 42, 44, 46, 48, 50 sothat each opening is associated with one port, and seals against aninterior surface of housing 40 that defines cavity 56, around theopening of the port into cavity 56. Opening 20 and 22 in shell body 58,however, are selectively alignable with ports 42, 44, 46, 48, andopening 24 is aligned with port 50 to govern the flows between theports. The shell body 58 includes a valve stem 64 (see FIG. 7) whichextends through an opening in housing 40. This valve stem, and in turnthe remainder of shell body 58, is rotatable about axis by an actuatoras discussed above.

A plurality of port bodies, namely, a first port body 224, a second portbody 226, a third port body 228, a fourth port body 230, and a fifthport body 232 (see FIG. 7) are respectively received in the firstthrough fifth ports 42, 44, 46, 48, 50 as illustrated. The port bodies224, 226, 228, 230 are substantially identical to one another, but portbody 232 differs in the illustrated embodiment. Port body 224, 226, 228,230 includes a through bore 238, 240, 242, 244 which communicates withan internal cavity 56 containing shell body 58 rotatably disposedtherein through port 42, 44, 46, 48, respectively, of housing 40. Portbody 232 provides passage through port 50 of housing 40 as shown in FIG.7.

Having now described the structure of an embodiment of the presentinvention, attention will now be directed to the orientation of theshell body 58 in each of FIGS. 1-6 to discuss the fluid control providedby rotation thereof.

As shown in FIG. 1, the shell body 58 is located in a first positionreferred to herein as 0°. In such position the openings 20 and 24provide fluid communication between ports 48 and 50 (see FIG. 7) andprovide a change in the axis of flow between the two different planes inwhich the ports 48 and 50 lie. In this position the opening 22 providesfluid communication between ports 42, 44, and 46. This communication isequal between ports 42 and 44, and may provide a 50%-50% mix of fluidflow from ports 42, 44 into port 46, or vice versa, in certainimplementations. Indeed, the percentage mix or flow can be variedbetween the ports 42, 44 by rotating the shell body 58 to provide agreater or lesser communication with opening 22.

Once the shell body 58 has rotated about 24° in the illustratedembodiment as shown in FIG. 2, port 44 is isolated such that it has nofluid communication to any of the other ports. However, fluidcommunication is still provided between ports 42 and 46 (and between 48and 50). A rotation of the shell body 58 about 24° from the orientationof FIG. 1 in the other direction as shown in FIG. 3 isolates port 42such that it has no fluid communication to any of the other ports.However, fluid communication is still provided between ports 44 and 46(and between 48 and 50). As the angle of rotation is varied, the area ofthe openings 20 and 22 that is exposed to the particular port alsovaries once an edge of the opening moves past the seal 60 edge.

FIGS. 4-6 illustrate similar rotational alignments as shown in FIGS.1-3, but starting with an orientation of the shell body 58 that is 180°from that shown in FIG. 1. Such orientations provide fluid communicationbetween ports 46 and 50, and variable mixing (or division) of flowbetween ports 42, 44, and 48, as well as isolation of ports 42 and 44 asdiscussed with regard to FIGS. 2 and 3.

With the symmetrical layout of the four ports 42, 44, 46, 48 and theopenings 20, 22, similar operation will become apparent to those skilledin the art from the foregoing when the shell body 58 is initiallyoriented at 90° and 270° from the orientation shown in FIG. 1, and adiscussion thereof will be forgone in the interest of brevity.

FIGS. 7, 8 provide isometric side views of the embodiment of themulti-port multi-plane valve 32 shown with the shell body 58 positionedas shown in FIG. 1 when viewed into port body 224 and 228, respectively.FIG. 9 provides isometric side views of the embodiment of the multi-portmulti-plane valve 32 shown with the shell body 58 positioned as shown inFIG. 2 when viewed into port body 228.

Turning now to FIGS. 10 and 11, there are illustrated isometric views ofan embodiment of a multi-port multi-plane valve similar to thatdiscussed hereinabove. However, the reference numerals have been removedand replaced with five port designations 1-5 to simplify theunderstanding of the operation thereof for the following description. Inorder to aid in this description, the isometric cross-sectional view ofFIG. 12 is also instructive as it illustrates the internal passages andthe shell body with the same five port designations 1-5. Further, FIG.12 and the figures included thereafter introduce flow arrows and blockedflow symbols to aid in the understanding of the operation of the valve.However, it should be noted that the directional heads of the flowarrows shown in FIGS. 12-20 are not limiting on the flow directionthrough the valve, but instead only illustrate possible flows throughthe valve based on the communication enabled by the positioning of theshell body. Indeed, flow in other directions is also possible based onthe external plumbing and flow system, and flow in both directions atdifferent times through the same ports based on these external factorsis also possible.

Turning now to FIG. 13, the shell body is located in a first positionreferred to herein as 0°. In such position the shell body provides fluidcommunication between ports 3 and 5, and fluid communication betweenports 1, 2, and 4. As the shell body is rotated, the percentage flow canbe varied between the ports 2 and 4 to provide a greater or lesser flowfrom port 1.

Once the shell body has rotated about 24° in the illustrated embodimentas shown in FIG. 14, port 4 is isolated as shown by the blocked flowsymbol such that it has no fluid communication to any of the otherports. However, fluid communication is still provided between ports 1and 2 (and between 3 and 5). A rotation of the shell body about 24° fromthe orientation of FIG. 13 in the other direction as shown in FIG. 15isolates port 2 as shown by the blocked flow symbol such that it has nofluid communication to any of the other ports. However, fluidcommunication is still provided between ports 1 and 4 (and between 3 and5).

FIGS. 16-18 illustrate similar rotational alignments as shown in FIGS.13-15, but starting with an orientation of the shell body that is 180°from that shown in FIG. 13. Such orientations provide fluidcommunication between ports 1 and 5, and variable flow between ports 3,2, and 4, as well as isolation of ports 4 and 2 as discussed with regardto FIGS. 14 and 15.

With the symmetrical layout of the four ports 1-4 and the openings inthe shell body, similar operation will become apparent to those skilledin the art from the foregoing when the shell body is initially orientedat 90° and 270° from the orientation shown in FIG. 13, and a discussionthereof will be forgone in the interest of brevity.

With reference now to FIGS. 19 and 20, there is illustrated anembodiment of the multi-port, multi-plane valve that includes a shellbody having a first and a second flow enhancer channel 20A, 20B providedon either side of the opening 20. These flow enhancer channels 20A, 20Balso provide fluid communication to opening 24 leading to port 5, andoperate to increase the flow thru the right angle opening when the shellbody has been rotated to a position that is blocking the flow throughone of the ports (4 in FIGS. 19 and 2 in FIG. 20) on the other side ofthe valve. Such enhanced flow reduces the pressure drop occurring on oneside of the valve when controlling flow paths on the other side of thevalve. In embodiments, opening 20 is wider than the first flow enhancerchannel 20A and wider than the second flow enhancer channel 20B.Further, in embodiments, the first flow enhancer channel 20A has thesame width as the second flow enhancer channel 20B.

As described herein, embodiments of the present invention The multi-portmulti-plane valve advantageously overcomes existing problems in the artby presenting an overall construction with a reduced part count, areduced number of potential leak paths, and a reduction in overallassembly time and cost. In embodiments, the multi-port multi-plane valvehas particular suitability for routing coolant in a thermal system,e.g., an engine or motor of a vehicle. For example, the multi-portmulti-plane valve can be used to route coolant in a first thermal loopand at least one other thermal loop. In embodiments, a first thermalloop may be to route the coolant to engine/motor components or a batteryin need of cooling or warming, and a second thermal loop may be providedto cool or warm the coolant (e.g., to a radiator, chiller, or heater).Depending on the particular needs of the coolant and the components towhich it is being routed, the shell body 58 is able to be rotated todirect the flow of coolant through the desired thermal loops.
